Press Release Summary:
Integrating photodiode sensor and 18 Hz chopper,Â Model RM9-PD measures power of very low level CW or quasi CW sources with response time of 3.6 sec. Sensor is calibrated over entire range of wavelengths, from 0.2–1.1 Âµm, rather than single wavelength. Featuring digitally synthesized lock-in amplifier that minimizes external noise, sensor can measure power levels from 300 fW to 300 nW.Â Output can be displayed on any standard Ophir meter or on PC or Android smartphone or tablet.
Original Press Release:
Ophir Photonics Announces Low Noise, High Sensitivity Radiometer for Measuring Very Low Powers Down to 300fW
San Francisco, CA – Ophir Photonics Group, a Newport Corporation company celebrating 40 years of excellence as the global leader in precision laser measurement equipment, today at SPIE Photonics West 2016 announced the RM9-PD Radiometer, a sensor for measuring the power of very low level CW or quasi CW sources. The RM9-PD integrates a photodiode sensor and an 18Hz chopper into an easy-to-use system that measures very low powers. The sensor is calibrated over the entire range of wavelengths, from 0.2µm to 1.1µm, not just a single wavelength. The sensor features a digitally synthesized lock-in amplifier that reduces external noise to a minimum; this allows the sensor to measure power levels from 300fW to 300nW. The output of the sensor can be displayed on any standard Ophir meter or on a PC or Android smartphone or tablet.
Designed for detecting very low power radiation, the RM9-PD Radiometer features an 8mm aperture and fast response time (3.6s with display).
To display measurements, the RM9-PD Radiometer can connect directly to any standard Ophir meter or PC interface. This means no additional power module is required, as is the case with traditional radiometers. The RM9-PD works with Ophir's StarLite, Nova II, and Vega smart displays, and Juno PC interface. The sensor also works with the StarViewer app that brings laser power/energy measurements to Android smartphones and tablets. The display is automatically configured and calibrated when plugged into one of the company's laser measurement heads.
The RM9-PD Radiometer is available now. OEM pricing is available on request.
